Customer Ratings & Reviews

This modem is doing exactly what I needed. Everything has been running smoothly. I have been on a lot of video calls, and I’ve never had any connection issues. The modem maybe feels/looks a little cheap, but it operates well, which is all that matters. It’s nice and compact too. I recommend this modem to anyone looking for something simple and effective.

I have been using this product over a year and it fulfills my need. I'm using for my 2 laptops, 2 phones, and TV.

I bought the Arris 6183 modem for my Optimum online connection. it worked really well till the time i replaced my old router and installed the new Eero pro wifi system. Arris 6183 is not compatible with Eero. Returned and got the Motorola MB7420 instead. This works like a charm. Giving me similar speeds as the Arris and much much better connectivity as compared to the Optimum modem. I highly recommend it

This Motorola modem replaced the cable company modem and saves me about $10 per month rental fee. It worked great right out of the box. All I did was hook it up, called Time Warner (now Spectrum) to activate it, and it has been working fine ever since. I shopped around and I'm very satisfied with the price, performance, good operating temperature, small size, clean design, and it even has a convenient on/off button.

This replaced the Arris provided modem I had from Comcast for YEARS of wasted monthly equipment rental charges. Will pay for itself within the 1st year. Since I dropped my Comcast phone service I did not need the telephony piece and a straight reasonably priced, fast modem was all I needed. This took my wired LAN desktop from 150mbps to 250mbps so an instant improvement. I'm a guy who dislikes combo modems and wireless gateways and prefer stand alone separate router for manageability and I have seen some speed gains there too. Time will tell how this holds up but so far rock solid. A quick ten minute call to Comcast to provide them the MAC address and activate and I was good to go.

My mother is currently unfamiliar with the required technology needed for todays internet. Bought simply because I am familiar with the brand. Packaged well and very simple to set up. Easily handles/ distributes internet nicely throughout our home. Our provider is Xfinity. Usually in our house there is an Xbox one, a few laptops and/or cellphones actively in use.

I bought this modem as part of switching to Comcast about a month ago and have had no issues at all. The indication saying it is supported by them is true and activation went smoothly. If you want to save $10 or so a month on modem rental fees and are on a provider or are switching to a provider that uses DOCSIS 3.0 then this is worth every penny!

So, you're looking for a new modem. Your old one stopped working--started dropping connection randomly--and you just want to buy something that works without spending too much money. I get it. I really do. But, there's a marginal chance you have very little knowledge about networking. Fair. Who has time to learn all that? Here's the bottom line: The Motorola MB7420 is made by a trusted company (you've at least heard of them). But why buy this model and not the slightly cheaper MB7220 you saw on that other website or in your local catch-all retail store? Channels and speed, to put it simply. If you're paying for a mid-level internet plan (because you like streaming videos/playing video games/looking at fourteen separate Firefox tabs of cat photos) and you're not the only person in your house doing this, you need the capabilities provided by this model. See that "16x4" on the box? Equate those numbers to (number of people)x(balls being thrown around)--bear with me here. You're probably thinking, "Four balls isn't that many. Surely eight people could toss and catch balls just as easily as sixteen." Think again. Imagine that each of these people is throwing these balls at near light-speed(they're really good at catching and throwing). Now imagine that sometimes multiple balls are directed at one person. See where I'm going with this? If not, use your rudimentary math skills: sixteen is twice as much as eight. This means a drastically reduced chance of multiple connections causing a drop in speed on your devices. Do you like buffering? Maybe you do. Maybe that spinning circle puts you in a zen state of mind. If not, stop being cheap and buy a decent modem.

Using for Xfinity Extreme 150, paired with NETGEAR Nighthawk X4S - AC2600. Kids have finally stopped complaining about lag and slow internet. Latest OOKLA - 11 ping/180 download /23 upload. Started using in late August 2017, still good in November 2017. Will update if any issues. So far so good!

My older cable modem was only 8x4 channel bonding capable. If you don't know what that means, it means that on the download frequency that the cable companies use in their cable system for delivering internet data it was only capable of locking on to and combining up to 8 channels. Basically, the more available channels the more reliable and faster (depending on your Internet Service Provider's provisioned speed) internet connection due to wider available bandwidth. For some reason, my old modem was only able to lock on to 4 download frequencies. After I upgraded to this modem, I have 16x4 confirmed channel bonding. Yes, I know this all sounds very geeky but basically think of it this way.... 4 lane highway vs 16 lane highway... when your internet service provider is sending data to you and it has more lanes to pick when traffic gets congested that means less wait time and more reliable data transfer. My ISP is Spectrum and I can confirm that my channel bonding is at 16x4 with this modem. But please note... your connection may vary due to your Internet Service Providers speed and data connection provisioning on your account

The Motorola cable modem MB7420 replaces a 10+ year old Motorola Surfboard Extreme cable modem SB6121 that never quit working but was simply becoming obsolete. I've had excellent luck with the quality and dependability of Motorola cable modems and highly recommend them. This modem is fast, dependable, and I appreciate the on/off button so that the modem is not on 24/7.

We got this modem to replace the standard modem provided by the cable company. It outperforms their modem and integrates beautifully with out wireless gateway.

Bought it as a replacement for my older unit to keep up with the speed. Easy set up and so far works great. Had Motorola before and it's a brand I trust.

This modem has been very dependable and helps my system run faster. It can keep up with my router, which is key because I also work from home.

We finally got modern internet service! When I went to buy the cable modem I selected based on ratings and price, the Best Buy salesman recommended this one instead because it "plays well" with the Wave service I have here in western WA. The Wave technician agreed when he hooked up the service. A cable modem works best when you don't notice it - solidly functioning in the background. This modem has worked well for us for the month its been in service, even recovering itself after a power outage.

I was having connectivity issues with the Arris modem supplied by Spectrum/TWC so I decided to get my own. I originally got a Netgear CM500 but it wouldn't connect to Spectrum so I got this. It took about 5 minutes to set up and another 10 minutes on the phone to get it provisioned. I'm getting 100G+ downstream and 12G upstream compared to less than 50GB downstream and 5GB Upstream with the Arris. Connecting the router was a simple 10 minute task as well. Performing better than expected.

I have had this modem about 1 week and so far, it is running great. I use a separate modem and router and it makes my internet load faster. Setup was easy and simple. Phone call to Comcast to register device with them took the longest, but that's expected. Two thumbs up. Make sure you stand it upright and don't lay it on it's side. It has a stand but I tried to lay it on its side and it started to get hot. So I stood it upright and it cooled right down. Just an FYI

I bought this modem at the recommendation of the Best Buy staff and it does exactly what I want. I had the lower model version previously and this one seems to allow faster internet.

Stylish - check performance - check install issues with ISP - none

Does the job; works with Time Warner as they recommended it. Setup with them took a call and 10 or 15 mins on the phone, so wasn't as painless as I would have liked, but post-setup, been working fine. I haven't tested the ultimate speed range of the unit, but no reason to believe it doesn't perform as advertised -- I'm using it with a 50M download speed without problem. Buying the modem much better than renting from TWC.
